How do you like drivability on the 3.92? How much power are you running?
I have the 3.77 r&p that came with my LSD diff waiting in a box but I'm strongly considering going with 3.92 when I get to my engine swap.
drivability is fine. a few horse shy of 400whp. my mpg is about 19hwy and 17town before it was 26hwy and 20 town. stock 2jzge with w58 with 4.10:1 the 3.92 is fine for daily. 4.10 was fun for rolling burnouts and the 4.30 was to short for daily. ill be going to a 3.73 when i find one and try a cruising tune to increase MPG. $50 in fuel a week sucks.
